Wolfgang Van Halen is the frontman, guitarist, drummer, bassist and songwriter for the band Mammoth. Yes he plays all the instruments on their albums, Mammoth III just came out. On stage though Wolfgang has a plethra of amazing musicians backing him up. 

Myles Kennedy is the lead singer of Alter Bridge who's new album AB is due out in January. He's also the lead singer for Slash Featuring Myles Kennedy and the Conspirators. When he's not busy with those projects he has is own solo band. 

Mammoth are on tour until mid December with Myles opening up the shows and I had the pleasure of joining them on a recent tour stop that ended with a conversation in Myles' dressing room with both of them.
